FERTILIZER-DISTRIBUTE? FOR GRAlN-DRiLLS.

SPECIFICATION forming part of Letters Patent No. 308,973, dated August26, 1884.

Application filed May 13, 1884. (K inodel.)

To all whom, it may concern:

Be it known that I, LEANDER BECKER, of York, in the county of York andState of Pennsylvania, have invented certain new and useful Improvementsin Fertilizer-Distributers for Grain-Drills; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification, and to the figures and letters of reference markedthereon.

My present invention relates to that class of fertilizendistributersusually employed in connection with seed-drills or corn-planters; and itconsists in the several combinations, constructions, and arrangements ofparts, as hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a rear view of my improvedattachment as applied to a sccd-drill; Fig. 2, a bottom plan view; Fig.3, a transverse section on the line a a, Fig. 2; Fig. 4, a top, and Fig.5 abottom, view of the plate of frame to which the feeddisl; is applied;Fig. 6, a section on the line 3 Fig. 2, with the sustaining andadjusting lever swung downward. Figs. 7 and 8 are details of the cut-offand its operating mechanism.

Similar letters of reference in the several figures indicate like parts.

The box or hopper A, of any ordinary wellknown construction, has boltedor otherwise secured to it the frame or plate 13. This plate is providedwith a dependent concentric flange, b, projecting through and below thebottom of the hopper, and with one or more inwardlyproiecting cups orconduits, Z), open at the bottom and one side, and provided with ascraper or flange, If, at the other side.

Beneath the plate B, and fitting snugly against its flange b, is therotary feed-disk 0, upon which the material rests and is carried intoand delivered through the conduits b. The

disk 0 is preferably constructed with a raised central portion, 0, todirect the material toward and upon the flanges c, and the flange Z) ofthe conduit is made to conform to the surface of the disk with which it(to-operates. The disk is also preferably provided with studs orprojections 0 and the flange If with a notch or opening for theirpassage, whereby the material resting upon the disk is kept in motionand prevented from cloggingor eaking. The disk, when set in motion,carries the material resting upon its surface into 'or under the projecting conduit, and the flange Z1 being set tangential to the axis ofmotion, diverts the material into the openings 2), from whence it passesthrough the boots of the seeder.

In order to stop or limit the discharge from the conduit, I havearranged a cut-off or sliding gate, D, adapted to close the passage-waybetween the conduit and opening I). Said out off is attached to a bar,(1, supported in suitable guides, and pivoted to a bar or rod, 61,extending the length of the hopper. Projecting between two pins orrollers, (1 attached to said rod (2, is an inclined sector or cam, D,mounted upon the rotating shaft I)", through the movements of which thedrills are elevated, the several parts being so connected and arrangedthat when the drills are elevated the gate will be closed and the feedstopped so long as the drills remain elevated or inactive.

In using a disk-feed of the kind above described great difficulty isexperienced in maintaining a tight joint between the disk and the plateor casing, owing to the rapid wear of the parts, the disk soon gettingloose,which not only interferes with its operation, but allows thefertilizer to escape at the sides or edges. In order to overcome or in agreat measure obviate these difficulties, I have mounted the disk andits operating-gear upon an adjustable arm or support, E. The support Eis bifurcated at one end, and pivoted upon a rod, 0, passing throughears or bean ings attached to the plate 13 or to the hopper, while theopposite end of said support is ad justably fastened or held inproximity to a lug, e, by the thumb screw 6 At or near the center of thesupport E is formed a bear ing for the reception of the spindle of thepinion or worm wheel E in gear, when elevated, with the worm I orequivalent driving mechanism.

Upon the upper face of the wheel F is formed a center pin, f, carrying arubber or other spring-cylinder, f, and an inclosing-ring, f, providedwith one or more offsets or lugs, f

On the under side of the feed-disk O is formed a collar, g, adapted toenter between the spring f and ring f on the wheel F, suitable notchesor slots being formed in said collar for the reception of the lugs f.

It is obvious that as thus constructed and arranged the disk can bereadily removed or replaced independent of its supporting and operatinggear by simply releasing and dropping the support E. Moreover, the diskis held to its seat by an elastic pressure, which can readily be adjusted by means of the thumbscrew, so as to compensate for wear andalways maintain a close joint, a very important feature in this class ofmachines.

The bearings for the shaft I-I, carrying the worm or other driving-gearand the guides for the rod (1, are attached to the plate B, as is alsothe lug 0', through which passes the adjusting-screw; hence all theoperating parts are united and supported upon a single plate or frame,and the whole is adapted to be applied to the hopper Without furtherfitting.

IVhen two or more feed-disks are employed on the same or contiguoushoppers, as shown in Figs. 1 and 2, the shaft H and rod (1 are continuedacross and supported in the bearings formed on or attached to theseveral plates.

Having thus described my invention, what I claim as new is 1. In afertilizer'distributer and in combination withthe hopper thereof, thedetachable plate B, with its vertical flanges and inwardly-projectingconduit, and the rotating feeding-disk mounted upon a support hinged tothe said detachable plate, substantially as described;

2. In combination with the plateB, its-dependent flanges, and inwardlyprojecting flanged conduit, the rotary feeding-disk provided with spursor lugs, substantially as described.

3. In combination with the rotating feeddisk, the operating-gear, theintermediate clutch, and the sustaining-spring, substantially asdescribed.

at. In combination with the feeding mechanism, the cut-off,connecting-rod, sliding bar, andinclined sector D, mounted upon thedrillelevating shaft, substantially as described.

5. In combination with the operating-gear provided with a spring andclutch and mounted upon a-pivoted support, the removable feeddisk,substantially as described.

7 6. In combination with the plate and its de lugs or shoulders, asdescribed, in combination with the feeding-disk and its notched ring,substantially as described.

9. The pivoted and adjustable support carrying the worm-wheel andfeed-disk, in combination with the wormshaft, substantially asdescribed.

10. The bifurcated support pivoted to the plate B at one end and held byan adjustingscrew at the other, in combination with thecentrally-located gear and rotary feed-disk, substantially as described.

11. In combination with the rotary feeddisk, its operating-gear, andintermediate clutch and cushion, the adjustable bifurcated arm orsupport pivoted to the plate B near the worm-shaft, substantially asdescribed.

'12. In combination with the plate B, cut

off, rotary feed-disk, and operating-gear there for, the pivotedsupport,worm-shaft, and sliding bar, all mounted upon the plate B,substantially as described.
